Maybe it’s just because I got lost through a lot of emails, and Mail.app
doesn't really thread these emails properly, but I can’t understand the
resistance of the front-up parsing.
I think we are just discussing if there is any way to not parse the whole buffer up front. (Which I consider unlikely because of the nature of parsing.) The current shipping CC-Mode is parsing most of the code front-up, and
clearly tree sitter will be faster than that. AFAIU parsing code only by
only looking through a peephole is super hard except for some languages
that are designed for peephole processing - and that makes it only hard,
not super hard.
Some modes doesn’t require a font-up parsing. IIRC, an example from an earlier message is _javascript_-mode.
